Title (EN) DISCOVERY SIGNAL TRANSMISSION IN CELLULAR SYSTEM
(FR) TRANSMISSION DE SIGNAL DE DÉCOUVERTE DANS UN SYSTÈME CELLULAIRE
Abstract:
(EN) There is provided a solution for transmitting periodic signals in a cell. According to an aspect a method comprises in a network node: generating a plurality of radio beams in a cell, wherein said plurality of radio beams comprise a plurality of beamforming configurations, and wherein at least one radio beam comprised in the plurality of radio beams comprises a discovery signal transmission; determining, for the at least one radio beam, whether or not at least one terminal device is located in a coverage area of the at least one radio beam; defining a transmission periodicity of the discovery signal transmission on the basis of said determining.
(FR) L'invention concerne une solution permettant de transmettre des signaux périodiques dans une cellule. Selon un aspect de l’invention, un procédé implémenté dans un nœud de réseau comprend les étapes consistant à : générer une pluralité de faisceaux radio dans une cellule, ladite pluralité de faisceaux radio comprenant une pluralité de configurations de formation de faisceau, et au moins un faisceau radio de la pluralité de faisceaux radio comprenant la transmission d’un signal de découverte ; déterminer, pour le ou les faisceaux radio, si au moins un dispositif terminal se trouve dans une zone de couverture du ou des faisceaux radio ; définir une périodicité de transmission de la transmission du signal de découverte sur la base de ladite détermination.
